Answer: First, write the equation,
t² - 15 = 0
Now, we shift the (-15) to RHS,
t² = 15
So, t = - √15 = -3.87 or + √15 = + 3.87

Answer:
168 seconds
I edited the answer.
Step-by-step explanation:
To find the the time taken for both lights to flash at the same time, we need to find the lowest common multiple of 28 and 24.
28 x 6 = 168, 24 x 7 = 168
The LCM of 28 and 24 is 168.
So it takes 168 seconds for both lights to flash at the same time.
Answer:
x = 1.5
Step-by-step explanation:
-1.2 (3 - x) = -1.8
<em>Apply distributive property</em>
-3.6 + 1.2x = -1.8
<em>Get 1.2x alone so add -3.6 to each side</em>
1.2x = 1.8
<em>Get x alone so divide 1.2 on each side</em>
x = 1.5
Hope this helps!
